MLS1806-4S4-151

Overview

The Ferroxcube MLS1806-4S4-151 is a surface-mount ferrite bead designed for electromagnetic interference suppression in compact electronic circuits. It features an 1806 package dimension of 4.5mm length, 1.6mm width, and 1.6mm height. The component utilizes 4S4 material to provide an impedance of 150 ohms at high frequencies while maintaining a low DC resistance of 0.2 ohms. It supports a continuous current rating of 500 mA with a tolerance of ±25% and operates within a temperature range from -55°C.

Feature Summary

• Provides effective attenuation of high-frequency noise signals through integrated ferrite material properties
• Enables space-constrained circuit designs via compact surface-mount packaging geometry
• Maintains signal integrity by offering low direct current resistance during normal operation

Applications

• Electromagnetic interference suppression in portable consumer electronics
• Noise filtering on power supply lines in communication equipment
• Signal line protection in automotive electronic control units

Procurement Notes

Verify the specific material grade suffix (4S4) and impedance value (151) against the official datasheet to ensure compatibility with target frequency ranges. Confirm that the 500 mA current rating meets the operational requirements of the specific circuit application. Check for RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when high-frequency noise suppression is required in tight spatial constraints. Ensure the operating current does not exceed 500 mA to prevent saturation or thermal issues. Verify that the 150 ohm impedance characteristic aligns with the noise spectrum of the application. Consider the -55°C minimum operating temperature for harsh environments.

Part Context

This ferrite bead belongs to the MLS series, which offers various sizes and materials for EMI suppression. Ferroxcube provides these components as part of a broader portfolio including cores and inductive elements. The series supports design goals for miniaturization and low loss in energy conversion and signal processing applications across multiple industries.

Replacement Considerations

Consult official Ferroxcube documentation for verified substitute part numbers within the MLS series or other compatible families. Do not assume interchangeability based solely on package dimensions or general specifications.
